Royer, M. EPA Field Demonstration of Innovative Condition Assessment Technologies for Water Mains at Louisville, KY - slides. Presented at Condition Assessment Workshop, Vancouver, BC, CANADA, January 15 - 17, 2013.

Impact/Purpose:

To be presented at a condition assessment workshop in Vancouver, Canada on Jan 15, 2013 (and then Jan 17 in Seattle, WA)

Description:

This presentation will describe a series of field demonstrations of innovative leak detection/location and condition assessment technologies that was sponsored by the U.S. Environmental Protection Agency (EPA), conducted by EPA’s contractor (Battelle), and hosted by the Louisville Water Company. Six vendors (PPIC, Pure, Echologics, Rock Solid, AESL, and Russell) operated their inspection devices and provided inspection reports. The demonstrations were conducted on a 76-year-old, 2,057-ft-long portion of a cement-lined, 24-in. cast iron water main that was scheduled for replacement. Three leak detection/location devices and nine pipe wall assessment devices were demonstrated. The leak detection/location technologies included: a tethered in-line acoustic device, an untethered in-line acoustic device, and an external acoustic leak correlator. The nine pipe wall integrity assessment technologies included: three average-wall-thickness-screening devices based on leak detection platforms, three external inspection technologies, and three in-line inspection technologies. The main goal of the demonstrations was to acquire a snapshot of the current performance capability and cost of these innovative technologies under real-world pipeline conditions so that technology developers, technology vendors, research-support organizations, and the user community can make more informed decisions about the strengths, weaknesses, and need for further advancement of these technologies.
